Wildlife and Terrestrial Species

Mottled ducks rely on the coastal marshes of the Texas Chenier Plain, which are considered among the most critically endangered habitats in the United States. USGS scientists are evaluating what might be contributing to the degradation of high-quality mottled duck habitat to better understand the causes of habitat loss and subsequently mitigate those losses.

The Nonindigenous Aquatic Species (NAS) program has developed a new tool, the NAS Alert Risk Mapper (ARM), to characterize waterbodies in the conterminous U.S. and Hawaii at potential risk of invasion from a new nonindigenous species sighting.

USGS is working with partners to understand how the federally protected Florida manatee population changes over time and responds to threats.

The American woodcock is a popular game bird in much of eastern North America. The woodcock population declined between 1968- 2000 at an annual rate of 2.3% in the Eastern region and 1.6% in the Central region. Estimated annual survival of woodcock banded in the Eastern region was estimated to be 0.354 for the period 1967-74. Estimates for the migration period, a period when substantial mortality...

We are working closely with multiple partners to provide updated information, model potential outcomes, and identify key uncertainties relevant to amphibian and reptile species proposed for listing in the northeast US. We also provide timely science to partners to assist in recovery of listed species, which may involve field research, data analysis, or decision support.

Commercial beekeepers have been bringing their bees to the Northern Great Prairie (NGP) for many decades due to the availability of nectar and pollen-rich plants in abundant grasslands.

Collisons between wildlife and vehicles threaten many species, and can lead to human loss of life, injuries, and loss of property. USGS is developing models to help evaluate the effectiveness of wildlife protection zones and optimize the design of these protected areas.

Pink-footed geese in Svalbard are a highly valued resource, but their increasing population causes conflicts with agricultural needs. USGS is devloping population models to help inform management of optimal harvest strategies.

USGS is applying decision analysis to identify cost-effective methods for controlling invasive species like the Argentine black and white tegu.

National Wildlife Refuges provide habitat for important fish and wildlife species and services that benefit coastal communities, like storm-surge protection. USGS scientists are helping coastal refuges plan for and adapt to sea-level rise.
